fix: bundle backend at publish time to resolve missing dependencies (#40)

When installed globally, backend workspace dependencies (like `yaml`)
were not resolved because only root package.json dependencies are
installed. Instead of duplicating every backend dep in the root, bundle
the backend into a single JS file via `bun build --target=bun` during
prepublishOnly. This inlines all dependencies so the published package
has zero runtime deps.
